When the magma cools and solidifies,volcanic rock. Reversals of the field give rise to a series of magnetic

岩浆冷却并凝固下来后，地磁场的方向和磁极被保留在磁化了的火山岩中。

Generally speaking, polarity does not remain only on one side of the pole forever; it vacillates from one side unto the other and should in fact have equal time, energy and focus on both sides .

一般而言，极性不会总是只停留在磁极的一边；它会从一边摇摆到另一边并事实上应该是以均等的时间和能量摇摆且聚焦在两边。

An appropriate balancing current and a set of indeplendent magnetic pole current can reduce magnetic coupling.
